Title: Evolution of Open Systems and Dynamical Semigroups
Speaker: Valentin A. Zagrebnov (Institut de Mathématiques de Marseille)
Abstract: We consider dynamical semigroups for unbounded Kossakowski-Lindblad-Davies generators corresponding to evolution of open systems. For this evolution we prove the existence of uniquely determined minimal trace-preserving strongly continuous dynamical semigroups on the space of states constructed by a regularisation à la Kato. We illustrate these results by a simplest example of the open quantum oscillator. The corresponding dual W*-dynamical system is unital quasi-free and (completely) positive automorphism of the Weyl CCR-algebra.
Time: Friday 27th January 2017, 2.00pm.
Place: Lecture Room, School of Theoretical Physics, DIAS, 10 Burlington Road, Dublin 4.

He is best known for work on particle acceleration in astrophysical plasmas and the origin of cosmic rays, but has broad interests in computational and theoretical astrophysics and more recently in issues of policy for science. Congratulations Luke 👏 (2/2)
